Description
Performance, Reliability, and Sound for your build…this is the exhaust manifold for your Mazdaspeed 3. You are looking at the only performance exhaust manifold that can fit 3 different turbo flange options: Stock Mazda Flange, T3 Flange, Precision V-Band and Tial V-Band. This modular design allows you to choose your flange style and change it later without replacing the entire manifold. Cast from 304SS, there are no welded flanges or connections that are prone to cracking and each flange surface is precision machined for flatness. Whether you are stock turbo or looking for the most powerful stock flange turbo, the CST6, this manifold supported 685 Whp with ease and don’t forget the specifically designed dumptube that makes life easy for you.
Power:
30-40whp gains over an XS Power V3 and faster spooling. This is the result of a well designed, high flow exhaust manifold. Power over the entire curve results in better drive ability and faster times at the track.
CAD Designed:
Each component is CAD designed and validated on car for fitment and performance. Three components: the manifold, flange elbow, and dumptube come together to create the most complete exhaust manifold kit available.
Runner Design:
The CorkSport exhaust manifold utilizes 1.59 inch inner diameter runner for superior high power flow and smooth radius bends to reduce exhaust gas velocity losses vs the sharp bends and 1.41 inch runners found on the XS Power V3 and similar tubular exhaust manifolds. Exhaust gas velocity and smooth flow are the keys to an efficient and powerful exhaust manifold design. Utilizing casting vs tubular allows us to optimize both of these critical aspects.
High Flow:
Through a combination of computer aided flow simulations and flow bench testing, the CorkSport Exhaust Manifold was optimized to increase peak flow capacity and thus performance. Flow bench testing at 28 inches of H2O showed an average CFM flow improvement of 45% over OEM and 33% over XS Power V3.
Bullet Collector:
A shallow 16 degree angle collector with a defined “bullet” point was utilized to increase flow efficiency into the turbine for improved peak flow and power. Paired with individual runner lengths that vary from 10.50 to 12.40 inches, the CorkSport manifold improves flow balance while maintaining the unique Mazdaspeed exhaust note.
Flange Selection:
The only exhaust manifold available today that lets you choose your flange style and change it later for minimal cost and headache. With a modular flange design you can choose a Stock, T3, PTE V-Band or Tial V-Band flange today and if you change your build in the future you only need the new flange elbow, not the whole manifold. Designed for standard 44mm V-Band External Wastegates.
Dumptube:
With the unique location of the EWG we developed a custom fit 2-piece dumptube that makes installation easy. You can add this optional dumptube and avoid the high cost and time to have a custom dumptube fabricated. Designed to work with most typical downpipe and turbo setups.
Manufacturing:
With the high heat and pressure demands put on the exhaust manifold; material and strength are critical. The CorkSport manifold is investment cast from 304 stainless steel with 0.50in (13mm) thick flanges and 0.20in (5mm) thick runner walls. This manifold is beefy so it can handle the high power high heat reliably.
- Vehicle Fitment: 2006-2007 Mazdaspeed 6, 2007-2013 Mazdaspeed 3.
- Designed in America: in Vancouver, Washington, in the Pacific Northwest.
- CorkSport Service & Support: 2-year limited warranty, full-color installation instructions, all necessary components, and knowledgeable telephone support at (360) 260-2675.
- 44mm EWG Block Off Plate & Clamp Kit for IWG turbos sold separately.
- Some downpipes may need relocation of the primary O2 sensor location for installation.
- Some downpipes may not work with the optional dumptube.
- Designed for 44mm External V-Band Wastegate (not included).
- Provided firewall heat shield does not work with RHD Mazdaspeed 3 Models
- Compatible with TMIC with modification to the rear mounting bracket and without the use of the manifold-mounted EWG. PTE V-Band, Tial V-Band (coming soon) and T3 flange locations are based on stock flange location. Review your turbine housing selection with this consideration.

The CS exhaust manifold is a huge improvement over the previous aftermarket exhaust manifold I had installed on my 2008 speed3. The build quality of the CS manifold is top notch, heavy duty and looks great. Install was a breeze (once I got the old one out) and the vband clamps in this kit make it much easier to remove/install the turbo if needed versus oem. Perfect for the engine build I am planning on my speed!
Raider
Easy install, and absolutely flowing better now than the OEM one!!

If your looking to spice up your engine bay or make some serious power this exhaust manifold is a must. Looks great, sounds great and most important adds some power that everyone wants. I did have to get a different downpipe to run it, the CNT DP doesn’t work with this manifold. It did give me the excuse to buy their 3.5 inch turbo back exhaust. Let me tell you this compo is a must. If you got the money doesn’t hesitate to buy this.

For those who are thinking if to purchase this manifold, let me tell you this part is second to none top notch quality, The sound is amazing, not to loud not to quiet. The construction and the quality is amazing, the best! For those who have cobb DP and are wondering if it fits and whether you have to relocate, I'm confirming you it fits perfect with alot of clearance, no need to relocate oxygen sensor. My car has not yet been tuned but even un-tuned i could feel the difference, that's taking into consideration that we did cs cams which is another part you must considered, car rolls very quick reaching rpms much quicker.

This is the best exhaust manifold on the market! Relatively easy install and looks amazing (although mine is now covered with their manifold blanket). This manifold is worth every penny.
Weston Johnson
The quality of this manifold is outstanding! not only does it look good and sound good, the engineering is well thought out. Those who wrench on their own speeds know the time Corksport is saving us when having to do a turbo swap, maintenance or any work relating to the manifold with the two piece design.
Sebastien Lopes
If you love the stock manifold sound but want to make big clean power this is the manifold for you! I make 750 plus HP on this, and it shows no signs of slowing down. Takes the abuse day in and day out!
Mateo
This manifold sounds so damn good, love the modular design makes installing super easy.
Symon Powlison
Corksport knocked it out of the park with this Exhaust Manifold! From top notch casting, to the performance gains and deep exhaust node, this manifold is amazing! it looks great, it sounds great, definitely one of my favorite purchases!

Cast, Modular, v-band configurations, arguably the best sounding exhaust with stock location, not sure there is an argument out side of "extreme competitive price that makes it fly off the stock shelves" for the Mazdaspeed 3
